A weightlifting belt hook to support additional weight during weight training. The apparatus is attached to the user's weightlifting belt via a hook and holds disk weights generally at the level of the thighs. A downwardly extending stabilizing member configured to extend over the pelvic area and provide an opening extends from the hook, and a weight supporting member extends upwardly and away from the bottom of the downwardly extending stabilizing member. Exercise disk weights are placed over the weight supporting member and rest near the bottom of the weight supporting member.
